RAIN-WATER CUT-OFF.

SPECIFICATION forming part of Letters Patent No. 422,770, dated March 4, 1890. p

. Application filed July 18, 1889. Serial No. 317,931. (No model.)

the course of the water passing through the downspout may be readily and easily changed at will, so as throw it either into the cistern or into the waste or overow pipe, as may be desired. I also provide an extended bearing for the movable part to give stability to the same and provide a diaphragm to prevent accumulation of water in the lower part of the same, which would tend to increase the weight and render the said movable part more difficult to turn.

To the accomplishment of such ends and 'to the production of a cut-off at a minimum cost, the invention consists in the peculiarities of lconstruction and the combination, ar-` rangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claims.

. The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thercomform a part of this specification, and in which-f Figure l is a central vertical section illustrating my improved cut-off applied to a downspout and a cistern and waste-pipe, and Fig. 2 is a like view of the cut-olf removed.

Referring to details of the drawings byletter, A designates a suitable shell, of any preferred 1naterial--tin or galvanized ironmof conical or funnel shape, and provided with apertures A' A2, preferably, though not necessarily, upon diametricallyopposite sides thereof. u

B is the overflow or waste pipe, having a hanged end B', which bears against and is secured to the shell in any suitable mannerture A2, the said pipes B C being shown as formed with elbows, although such construction is not essential. The pipe O is designed to eonnectwith the cistern or other reservoir into which it is designed to conduct the water, and the pipe B with the sewer or street or other suitable place to conduct the rain or overflow when the valve is turned, so as to shut off the entrance to the cistern-pipe, as will be hereinafter explained. The upper edge of the shell A is turned over, as shown at A3, to strengthen the same-a common expedient in sheet-metal articles.

D represents the movable portion or cutoif. It is formed of any suitable material and of a corresponding shape to that of the shell. It is provided with a vertical eXtension D to receive the lower end of the downspout E, as represented in Fig. l. This movable portion is provided with an aperture D, as shown more clearly in Fig. 2, designed to register with eithel` of the apertures A A2, as may be desired.

D4 is a diaphragm within the portion D, se cured to the inner wall thereof in close proX- imity to the bottom of the aperture D3. 'llhis provides an air-chamber D5 in thebottom of the said movable portion D, while giving the same an extended bearing to steady the same and prevent wabbling thereof when it is turned. This diaphragm also prevents the accumulation of water in the lower part of the movable port-ion D, which would tend to increase the weight thereof and render it more difficultA to manipulate.

ln practice the parts are assembled as shown in Fig. l, and normally the movable part is so set in relation to the other parts that its aperture Dlf3 registers with the aperture A2, and consequently with the cisternpipe, so that water entering the downspout.

finds its way through the apertures into the 'said cisternepipe, the entrance of the overflow or waste pipe B being closed by the imperferate wall of the portion D. ,Vhen the cistern becomesfull, or for any other desired reason it is desired. to stop the inflow of water tothe same, the portion D is turned in the shell so as to bring the aperture Da thereof coincident with the aperture A the said action closing the aperture A2 and making the communication direct from the downspout out through IOC) i l. The combination, with the conical shell.

having apertures in its side walls, of the conical hollow revoluble portion iitted within the shell and adapted to be held therein by frictional contact of the Walls, said conical I portion being` provided with a side aperture and upwardly-extendingneck to embrace the downspout, and a closed chamber beneath the aperture, substantially as and for theipurpose specified.

2. The combination, with the conical shell having apertures in its side walls, and pipes,`

as B C, having` flanged ends and secured to said conical shell at said apertures, of a conical hollow rcvoluble portion tted within the shell and adapted to be held therein by fricy tional contactr of t-he Walls of the two parts,

and provided with an upWardly-eXtending neckD to receive the downspout, and with y-a side aperture in its taperedwalls, with a closed chamber beneath said aperture, substantially as and for the purpose specified.

In testimony whereof I afliX my signatu re in V presence of two witnesses. y
